Description

The skin treating system

Technical field

Present disclosure relates generally to apparatus and/or the local ointment (topical ointment) of using that is used for skin treating.

Background technology

Light emitting diode (LED) and laser instrument have been used for skin treating, for example, are used for the treatment of acne and reduce wrinkle.Most of existing Phototherapeutic device all is the large-scale price apparatus that is positioned in salon or the doctor's office.Patient's face is near machine, and machine is launched light laser or LED light then.Many these near infrared-ray treating device devices are all burnt the top layer of patient skin.The patient grows new skin layer again then, and new skin layer is more healthy and can comprise than the skin layer of removing before wrinkle still less.Independently Phototherapeutic device is too expensive for the patient buys for these, and is not to be intended for frequent regular use.For example, if all this high intensity laser beam is applied on patient's the skin every day, patient's skin will be by serious burn and possibility permanent damages.

There are other hand-held Phototherapeutic devices.In these devices some comprise LED, and LED is activated and towards user's skin.Very effective in the treatment that yet neither one is proved to be to skin in these hand-held devices--for example acne and wrinkle--.For example, as if low light intensity of using in these devices and wavelength can not kill the antibacterial that causes acne, the spontaneous recovery process that stimulates the skin that is subjected to the infection of acne flaw very effectively, or reduce wrinkle.Moreover all these hand-held devices all need to inject wall socket in operating process, so be not fully portable.Therefore, as if present hand-held Phototherapeutic device does not provide the treatment benefit of essence.

Introduction

Has therapeutic effect when the light of light emitting diode (LED) is on being applied to skin.The blue led light wavelength is approximately 475 nanometers (nm), and the red LED light wavelength is approximately 650 nanometers.Short blue light wavelength is more effective to skin surface, and has been identified and kills the antibacterial that causes acne.Long red light wavelength is easy to penetrate deep skin, and skin is had more revival should.

When together using, blue LED light can be used for killing bacteria and eliminates acne influence (effects of acne), and red LED light can be used for regenerating subsequently skin, and shortens the repair time behind the acne treatment.The system that describes below can be used for removing acne, but also can be used in other skin treating.For example, the light therapy system can be used to reduce aging effect and wrinkle, and can be used for usually skin is rejuvenated.

Making to use up to treat to remove acne, wrinkle and improve skin health and outward appearance usually, is a multiple process.For example, in the persistent period of continuous a couple of days, LED light is applied on the skin every day for several times.Light treatment therapy (light therapy treatment), particularly a difficult problem of light treatment therapy is at home, and the light treatment is not correctly carried out or by irregular or carry out inconsistently the course of treatment.

Because the light treatment hell to pay course of treatment, oversize or difficulty and correctly not carrying out too, the result of light treatment is blended at most.Even when the user uses Phototherapeutic device scrupulously, inconsistent and inappropriate still can the obstruction of the light energy of Phototherapeutic device output obtains satisfied result.

Fig. 1 shows relatively cheap optical curing device tool 12, and this apparatus has reduced complexity and time that the user implements the light treatment needs course of treatment, and higher performance and more consistent light treatment therapy are provided simultaneously.Therefore, apparatus 12 is more effectively treated acne, removes wrinkle and skin is rejuvenated than existing hand-held device.

The specific embodiment

Machinery and optics

Fig. 1 be hand, the back axonometric chart of portable, battery powered optical curing device tool 12, Fig. 2 is its top view, Fig. 3 is its front view.Apparatus 12 uses the HONGGUANG sent from light emitting diode (LED) 24 and the combination of blue light, is provided for the improved light treatment therapy of acne and general skin nursing.

Hand-held housing 18 comprises electronic circuit (seeing Figure 10 A and 10B), the light emitting diode (LED) 24 of a plurality of different colours of this circuit operation, and these light emitting diodes (LED) 24 is luminous with a plurality of different relative photo wavelength.Shell 18 is the cardinal principle dish type, and has flat substantially circular or oval-shaped end face 20 and bottom surface 22.Extend on every side circular outer rim 26 side 28 and rear end 30 at shell 18 between end face 20 and bottom surface 22.The socket 31 at 30 places, rear end is used for being positioned at the charging of shell 18 internal rechargeable batteries.

Grip 40 extends into the end face 20 of shell 18 downwards and has circle or elliptical shape, and this circle or elliptical shape are basic concentric with the circle or the elliptical shape of end face 20 and bottom surface 22.Grip 40 forms a circular ridge 42 of extending around the whole basically outer rim of shell 18.Button 16 starts this apparatus 12.

Transparent or semitransparent frontal lens 14 is attached to the front end 32 of shell 18, and the light guiding of the different colours that will send from LED 24 is to user's skin.Lens 14 have circle, ellipse, convex surface and cheese front 36 substantially, and extend between the side 28 of shell 18 in this front 36.Shell 18 and lens 14 form successive substantially circular front end 32.In one embodiment, the diameter of shell 18 between opposite flank 28 is about 78 millimeters (mm), and 30 length is about 79mm from the front 36 of lens 14 to the rear end.22 thickness is about 23mm to shell 18 to the bottom surface from end face 20.

In one embodiment, apparatus 12 just vibrates 29 when LED 24 operations.This provides feedback for the user, shows that carrying out a light treats the course of treatment.Vibration 29 also can provide minimal irritation on skin, inform where the treatment of user's light has been applied to.

With reference to figure 1-4, the shape of shell 18 is configured to be easy to hold and use in conjunction with the shape of lens 14, and more attractive in appearance than existing hand-held Phototherapeutic device.The disc of shell 18 makes when user's 50 handles are applied on the skin from the light of apparatus 12, and apparatus 12 can be caught and be handled by user 50 hands in any position almost.Grip 40 and formed ridge 42 further make user 50 to catch shell 18 better from forward and backward or side.

On on the face differently contoured that the novel curved shape of frontal lens 14 makes that apparatus 12 can the easier user of being pressed against 50.For example, acne often appears at the side and the below of nose 52.In these zones some are difficult to touch.For example, the light therapy apparatus with flat substantially front can not be properly fit onto the differently contoured zone around user's 50 noses.

The cheese of lens 14 makes that the bigger working region of these lens 14 can be by directly by on irregular face mask of the user 50.Simultaneously, the shape of lens 14, other reflection and light emission features in conjunction with the apparatus 12 that describes below are radiated these zonules that are difficult to touch on user's 50 healths with more substantial more equally distributed light energy.Therefore, the time less that provides light treatment more efficiently to need.

Fig. 5 illustrates the preceding profile of the front end 32 of apparatus 12, and Fig. 6 illustrates the top profile of the front end 32 of apparatus 12.Vertical aligned printed circuit board (PCB) 80 supports LED 24.In one embodiment, pair of

LEDs

24A and 24D are positioned at the place, the relative diagonal angle of the first couple of circuit board 80, and each LED sends the first identical color.For example,

LED

24A and 24D can be red-light LEDs.Second couple of LED 24B is positioned at the different place, relative diagonal angle of the second couple of circuit board 80 with 24C, and is configured to send second color identical, that be different from first color.For example, second group of

LED

24B and 24C can be blue-ray LEDs.

Certainly, might pair of

LEDs

24A and 24D can be blue-ray LED, and the second couple of

LED

24B and 24C can be red-light LEDs.In some embodiments, can use color except that redness and/or blueness.In some embodiments again, all LED 24 can be same color or LED 24 can be arranged to the pattern different with the rectangular pattern shown in Fig. 5.

LED

24A and 24C are positioned at first side of circuit board 80, and with the LED 24B of the second relative side that is positioned at

circuit board

80 and 24D about 14 mm distance 70 at

interval.LED

24A and 24B are positioned at the upside of circuit board 80, with LED 24C that is positioned at circuit board 80 downsides and 24D about 4 mm distance 64 are arranged.

Tubular sleeve 82 has rectangular cross-sectional shape, and surrounds all four LED 24.In one embodiment, sleeve pipe 82 has the width 92 of the length 86 of about 9-10 millimeter, about 27-28 millimeter and the height 90 of about 9-10 millimeter.Sleeve pipe 82 extends to the rear end of lens 14 from circuit board 80, so as substantially all light that send from whole LED 24 all with the form of the light 84 that is evenly distributed by the front end 83 of extraction lens 14.

Sleeve pipe 82 has roof 94 and diapire 96, and roof 94 is positioned at about 3 mm distance 62 places on LED 24A and the 24B, and diapire 96 is positioned at about 3 mm distance 66 places under LED 24C and the 24D.The first side wall 98 is positioned at about 6 mm distance 72 places beyond the left side of

LED

24A and 24C, and second sidewall 99 is positioned at about 6 mm distance 68 places beyond the right side of

LED

24B and 24D.

Sleeve pipe 82 can be formed by injection-moulded plastic, and has that high reflection is aluminized or the inner surface 100 of high polish mirror-polishing, the light of the multiple different colours that these inner surface 100 reflections are sent from LED 24.The structure of LED 24 causes also scioptics 14 of front end 82 that all light that send from LED 24 basically all are directed leaving sleeve pipe 82 in conjunction with it in reflection position in the sleeve pipe 82.This has sizable benefit, that is, use from most of light energy of LED 24 and with the leading face 36 of its guiding lens 14.

Have been found that and place red-

light LED

24A and 24D at the diagonal angle and place blue-

ray LED

24B and 24C, cause from the HONGGUANG of lens 14 and the more uniform distribution of blue light energy at two opposite diagonal angles.Further find, use the rectangular arrangement of LED 24 further to increase in conjunction with sleeve pipe 82, simultaneously the whole leading face 36 of more equally distributed light energy scioptics 14 from the total light energy of lens 14 outputs.

Fig. 7 illustrates the top cutaway view of sleeve pipe 82 and lens 14.Fig. 7 also show optical curing device tool 12 directly be pressed against before on the skin 51 of the user 50 shown in Fig. 4.The distance 102 of the particular range between LED 24 and the lens 14 provides the basic distribution uniformly on the front 36 of lens 14 of improved light check and correction (collation) and light energy.In one embodiment, the distance 102 in 14 front 36 is about 13 millimeters from LED 24 to lens.Yet the distance 102 in the scope of 10-16 millimeter still can be provided at the basic even light distribution on the front 36 of lens 14.

LED 24 is put from farther distance 102 places of lens 14, the positive outer more uniform Energy distribution of lens 14 can be provided.Yet, place LED 24 to such an extent that too far can cause light energy losses from lens 14.Therefore, 10-16 mm distance scope not only provides homogeneous energy distribution, but also makes and can launch from the front of lens 14 from a large amount of light energy of LED 24.In one embodiment, shown that 12-15 mm distance scope is optimum for homogeneous energy distribution and the high light energy intensity of maintenance.

In one embodiment, the lens 14 of apparatus 12 are designed to directly be pressed on user 50 the skin 51 when LED 24 emission light 84.For promoting this direct contact, in one embodiment, lens 14 are made by the medical grade plastics, VI level (Class VI) acrylic acid (acrylic), styrene methyl methacrylate copolymer or the UV stable copolyesters of described medical grade plastics as being made by IneosNova.(medial) copolymer is that a kind of making can be pressed into lens 14 on the skin 51 and do not infect or stimulate the optical-grade of opening (open) acne pustule in the middle of the VI level.Similarly acrylic acid, styrene methyl methacrylate copolymer material also can be used for making sleeve pipe 82, so that the high polish inner surface of being made by this copolymer will reflect away scioptics 14 from the light 104 of LED 24.Use press polished plastics thereby can eliminate the necessity of on the inner surface 100 of sleeve pipe 82, using reflective metals coating.

Other hand-held Phototherapeutic devices need the lens of user's handle assembly to be suspended in a distance on skin 51 surfaces.This might cause the non-homogeneous application of light energy.Because these other devices are maintained at skin top, make light energy also can shed to enter the environment away from user's skin 51 from the forward part of device.

As seeing among Fig. 7, sleeve pipe 82 extends to the back side 105 of lens 14 from LED 24, and will all enter skin 51 from all direct guiding of light 104 that LED 24 sends basically.LED 24 is placed on a accurate distance 102 places from lens 14 fronts, being used in combination sleeve pipe 82 makes all light from LED 24 all be funnel-form scioptics 14, simultaneously apparatus 12 can directly be pressed on the skin 51 in operation, these measures make user 50 can be own be applied to more equal light energies 84 of even unanimity on the skin.

Fig. 8 illustrates the amplification sectional view of lens 14.For promoting that further light energy 84 is distributed on the skin 51 more equably, lens 14 can comprise the veined back side 105 and level and smooth positive 36.Light 104 diffusions that the veined back side 105 will be sent from LED 24 at first, the light 84 of diffusion more is evenly distributed on the whole leading face 36 of lens 14.This has eliminated " dead band (dead-zone) " that has a small amount of light energy on the front 36 of lens 14.Projection 107 on the veined back side 105 of lens 14 in one embodiment can be high for about 0.025-0.100 millimeter, and can have various randomly shapedly, the described randomly shaped hot press operation of using in the forming process of lens 14 is formed in the back side 105.

Fig. 9 is illustrated in the different x-y position on the front 36 of lens 14, from the distribution of the light energy of red-

light LED

24A and 24D (Fig. 5) output.

The zone	Light energy (watt/square millimeter)
		119	189-203
120	175-189
		122	161-175
124	147-161
		126	133-147
128	119-133
		130	104-119

X axle 132 among Fig. 9 is represented the trunnion axis in the front 36 of lens 14.0 value of x axle is in the vertical centerline of lens 14, and the increment of 0 value both sides+/-5 and 10 is to be unit with the millimeter.Y axle 134 is represented the y axle in the front 36 of lens 14.0 value of vertical y axle is the horizontal center line of lens 14, and about 0 value+and/-5 increment is to be unit with the millimeter.

As can be seen, the levels of light energy of regional 120-130 representative all be evenly distributed in relatively lens 14 whole positive 36 on.When light 84 was applied to skin 51, this uniform light energy distribution caused more controlled and more effective light treatment.It should be noted that also higher levels of light energy is directed in the centre of lens 14, and only reduce a little towards the external corners of lens 14 subsequently.

There is not this uniform light energy distribution, will be in the different not commensurability light energies of lens position output.This may produce or hinder the treatment benefit to some skin areas, and produces insecure smooth therapeutic effect.In said system, all output equably on the entire working surface 36 of lens 14 of all basically light energies 84.Therefore, the optional position of lens 14 is applied to any skin area and all can provides essentially identical therapeutic effect.

The uniform distribution of light energy is the one or more result in the following factor as shown in Figure 9: around the reflection sleeve pipe 82 of LED 24, its basically all light 104 (Fig. 7) from LED24 all be guided out scioptics 14; LED 24 relative position relative to each other and their relative positions in sleeve pipe 82; LED24 is apart from the particular range of the distance 102 in the front 36 of lens 14; The light diffusion that produces by the veined inner surface 105 of lens 14; And from the specified quantitative of the light energy of LED 24 output.

Electronic device

Figure 10 A and 10B illustrate the circuit 200 of apparatus 12 inside that are used in Fig. 1.Programmable microprocessor 202 is used to control following different operating.Port 214, or different serial or parallel ports 204 can be used for the interior signaling in the access circuit 200 and communicate by letter with processor 202 or be processor 202 programmings.

Rechargeable battery 218 is inserted into battery folder 220, the electric weight in the LED 216A-216C pilot cell 218.In one embodiment, battery 218 is voltage chargeable AA nickel metal hydride batteries about the 1.2-0.9 volt.Voltage regulator 229 is when rising to 3.3 volts with voltage, for processor 202 performed measurements provide reference value.

Processor 202 comprises built-in storage, this built-in storage store instruction, and these instructions are performed subsequently so that different light treatment operations to be provided.Processor 202 is not only opened red-

light LED

24A and 24D and blue-

ray LED

24B and 24C, and able to programme control the time span that each LED 24 opens, and can control the cycle of operation (duty cycle) that is used to LED 24 power supplies in an alternative embodiment able to programmely.In another embodiment, LED 24 can be by processor 202 pulsed drive or with constant current driven under software control.When number of times, the user that processor 202 can also be followed the tracks of treatment course of treatment of being implemented before the user starts different HONGGUANG and blue-ray LED and how long they has been started, and at the different light treatment Smalt course of treatment and the output of red light energy.These information can be used to each user artificially or able to programme customize light treatment course of treatment.

Field-effect transistor (FET) 206 opened to start blue-

ray LED

24B and 24C by processor 202, and FET 208 is opened to start red-

light LED

24A and 24D by processor 202.When FET 206 or FET 208 were unlocked, FET 210 also was unlocked, thus Vibration on Start-up device 212.As describing among top Fig. 2, vibrator 212 produces vibration 29 in apparatus 12, and this vibration provides feedback, informs that at least one pair of LED 24 of user is activated and the light treatment is carried out the course of treatment.

It is novel that LED 24 is used to aspect the light treatment at it, and the light energy that they provide is higher than general obtainable light energy in hand-held battery powered light therapy apparatus.In one embodiment, blue-

ray LED

24B and 24C are the reddish blue LXML-PR01-175 of Rebel that is made by Luxeon, and has the wavelength of 455 nanometers (nm), 6.2 the running voltage (for placed in-line per two LED) of volt, the operating current of 120mA, the luminous power of 85 milliwatt/square centimeters, it produces 15.3J/cm in being installed in device the time ²Or 0.25J/cm ²Energy density.

In one embodiment, red-

light LED

24A and 24D are the red LXML-PD01-0030 of the Rebel of Luxeon, it has the wavelength of 632 nanometers and the wave-length coverage of LED is the 620-645 nanometer, running voltage is 5.06 volts (for placed in-line per two LED), electric current is 164mA, luminous power is 104 milliwatt/square centimeters, and energy density is 31.2J/cm ²Or 0.5J/cm ²First energy density values hypothesis rests on 5 minutes (300 seconds) of irradiation, a position, and second energy density values hypothesis apparatus 12 is at half surf zone (175cm of face ²) go up slowly and moved 300 seconds.

Energy density values can be programmed or variation by the operator according to user's skin type or according to any other desired therapeutic effect or skin.Above-mentioned LED 24 provides a large amount of light energies of improving the light therapeutic effect, yet, also can use the LED 24 of other types.

For the LED 24 at node 224 places, optimum operating value comprises the electric current of about 6 volts voltage and about 160ma.For the voltage from battery 218 is increased to 6 volts, processor 202 is at first by opening 222 chargings of 228 pairs of inducers of FET.When FET 228 was closed, the electric current that is stored in the inducer 222 flowed injection electric capacity 226 rapidly, and whichever LED 24 is started by FET 206 and/or 208.In the discharge process of inducer 222, electric capacity 226 keeps constant relatively voltage at terminal 224 places.

Define how much power at resistor 232 vertical read output signals 230 and just be applied to LED 24 by inducer 222.Processor 202 generates control signal 236, is sent out back processor 202 on which Input Online road 238 that this control signal 236 is determined from multiplexer 234.Processor 202 a stage to circuit 236 programming, so that read output signal 230 is imported at the mould-number that is fed on the circuit 238 to the processor 202.

Power level and target power threshold value able to programme that 202 of processors are relevant with voltage on the read output signal 230 compare.When

FET

24A and 24D this a pair of or FET 24B and this a pair of being activated of 24C, the voltage on processor 202 measurement circuitry 230.Processor 202 is dynamically adjusted the electric weight that offers inducer 222 according to the measuring voltage on circuit 230 then.

For example, if the electric current that passes through resistor 232 that inducer 222 produces more than 160mA, the voltage at resistor 232 two ends may be more than predetermined voltage threshold.Processor 202 is surveyed this high-voltage value on circuit 238, and correspondingly reduces the charging interval to inducer 222 during the next operational phase.If the electric current by resistor 232 is confirmed as certain amount less than 160mA, then the voltage on the sense wire 230 can be below a predetermined low threshold value.Correspondingly, during the next operational phase, the charging interval that processor 202 increases inducer 222.

With reference to Figure 10 and 11, processor 202 plays pulse-width modulator (PWM), produces the pulse wave signal 250 (BOOST_FET) with programmable frequency 252 (period T) and cycle of operation persistent period 254 able to programme.In cycle 252A, the inducer 222 among Figure 10 B is effectively being charged by battery 218 in the cycle of operation 254A, and is discharged among the LED 24 in time 255A.In discharge period 255A, signal 250 step-downs are closed FET 228, and electric charge in the inducer 222 are started enable (enabled) LED 24 and to electric capacity 226 chargings.

After several these charge/discharge cycle 252, processor 202 is measured read output signal 230.For example, processor 202 can per 8 milliseconds of measurement read output signals 230.If the electric current by LED 24 is too low, cycle of operation 254A is increased an increment, reaches cycle of operation 254B, and the period 255A that correspondingly discharges is reduced to persistent period 255B.After another 8 milliseconds, processor 202 remeasures the voltage on the read output signal 230, and according to the new measured value on the read output signal 230 or keep cycle of operation constant or adjust cycle of operation 254B.For example, if the voltage on the read output signal 230 is too high, cycle of operation 254B can be reduced an incremental time.

Therefore, processor 202 is very accurately controlled the electric current of giving LED 24.The light output of LED is directly proportional with the electric current by LED.This big relatively levels of light energy output from LED 24--provide as switching power circuit, strengthen the therapeutic effect of apparatus 12.This a large amount of light energy also produces from relatively little rechargeable battery 218.Therefore, the selective charge of 202 pairs of inducers 222 of processor and discharge make portable hand-held battery powered apparatus 12 that light treatment efficiently can be provided.

The charging of battery 218 is also by strict control.Voltage signal 259 from battery 218 is monitored by processor 202.Critesistor 260 is by processor 202 monitoring, determining the temperature of battery 218, and crosses at battery temperature and to stop battery 218 chargings when low or too high.

When charging read output signal 268 is connected to apparatus 12 by processor 202 monitorings to survey outside direct current (DC) power supply adaptor 264.When charging read output signal 268 indication power supply adaptors 264 are connected, and battery charging process (session) is when suitable, processor 202 activation signals 251 (CHARGE_FET).The signal 251 that is activated is opened FET 270, allows both inducer 222 also to be charged to battery 218 from the electric energy of power supply adaptor 264.

Voltage on processor 202 Monitoring Lines 262 is to keep constant charging current.This uses pulse-width modulator to realize in the mode identical with keeping the LED electric current.For example, the cycle of operation of the signal among Figure 11 changes according to the voltage on the circuit 262.A kind of termination of charge cycle in many ways: detect too high temperature, surpass the speed that temperature raises, surpass timer value, the voltage on the battery surpasses the value that limits, and perhaps cell voltage reaches maintenance level.
